The main objects of` this invention are to provide improved means vfor retaining avir' tically shiftablewindow` in adjusted position y without the aid of sash weights heretofore,

5 commonly employed; toprov'ide an improved window holder which may be attached to the Voutside of the window frame so as to obviate theuse of encasements heretofore employed for the sash weights ;V and to provide window tween the upper and lower window sashes .to serve as a guide, which'will present the outward appearance of the' ordinary stop stripsV and which may be conveniently installed as a unit in existing structures.

An illustrative embodimentofthis invention is shownin the accompanyingv drawings for frictionally grippingthe belt'. .Y

In the construction illustrated, the Window frame 1 comprises vertical side members 2 and horizontal end members v3V kwhich are mountedin a window opening in a wall 4. Mounted on the inner and outer edges ofthe side members 2 are molding strips 5 and 6 which extend the Jfull length of the windowV framev and abut against molding strips 7 Vand 8 on the top member of the frame. On theA eX` ternal face of each side member 2 and midway between the molding strips 5.and 6,7there is an elongated housing 9 secured to the side members by screws 10 and serving asA the usual middle stop strip separating` the holding means 'which maybe mountedbe is a horizontal section taken on thel spectively, which is mounted on the housing and bears on the innerV partofthe respectiveA belt, to produce' sufficient riction to? sustain V the weight of thesashl Preferably each side In the form shown, the improved window holdingY apparatus comprises an endless'belt movably mounted on the sides of the' windowv frameand arranged to'connect-the frame with L a vertically shiftable window sash, and means' groovcsll.fand712 in'which thelovver Y Y pervvindows slide ,f k.; A' pairfof Window sashes'13 and fltzare slidspectively.V Formed in the. lateral edges' of the sash'es 13 and 14 respectively are recesses 15 and-,16 which receive fthe opposite edges of the'housin'g 9thereby retaining'the'sashes' Y in their usual spaced relation.

The housings-9 vare preferably madefoij;

which. they may be slid. f y f u Inthe form shown vthe holding members comprise endless belts 17 and. 18 'which are 19V and 20V-respectively,located withinthe housings.,l The belt-17 passes through a pair of slots 21 in the wall of the housing adjacent .if

theupp'er sash and has Va lug 23 securedrto it and seated in a recess in the sash so that the belt travels rover the pulleys as vthe window sash is raised or lowered. s

rI he belt 18 isvcarried by-pulleys 20i'and passes outside of its housing through slots 22 .and is connected to the lower sash by a lug 24.

Each of the beltsis provided with a brake yably mounted in the guideways 11i and 12 ref vcarried on: upper and lower pairs of pulleys Y in the form of a resilient spring, 25 or'26 reof each sash is providedwith such window holding device.v

The pressure of the spring inany installa-V i 'Y i tion is designed to create ust enoughfrictionff between the inner'iiight of the belt andthe wall of the housing to oiifset the pull of grav-Y ity on the sash.

The improved window holding device ob-V viates the Vuse of sash weights and the wall compartments necessary to house and conceal them and thereby admits oa vgreater window width in` cramped placesvand also providesy asubstitute lthat can be readilyinstalled in old structures where spring bolt fastenersv have been used. s p

Although but one specific embodiment ,ci

this invention has been'iherein shown and de channel bars'to provide an elongatedhollow space vfor the window holding members which .v retain the window sashes in yany position, to

scribed, it will be understood that details of the construction shown may be altered or omitted Without departing from the spirit of this invention as defined by the following claim.

I claim:

ln a'. device of the class described, a: Window frame,` upper zidlower Window 'semelles-each having recesses in their lateral edges siidably.

mounted in said ra1ne,n guide member mounted on the side 'ofszid 'freine comprising a. channel for retaining said sasl-ies irl-spaced relation, a pair of belts lnovablylnounted'in said channeheach extending outwardly `on Y opposite sides thereof, means on eaclrbelt resilient members on'said' channel friet idly engaging* said belts for holdiin-gf.'i said sashesn'adjusted position? n' 'at Chicago this-ltl'ffdafy of June' connected with Ion-e of said'fsashes,1 aiV plairf oli signed 1929.'
